How do I convert ft³/lb back to gal/lb (US)?
Divide by the same factor — or equivalently, multiply by 7.48052. So 1 ft³/lb = 7.48052 gal/lb (US).
When would I need to convert US gallon per pound to cubic foot per pound?
Specific-volume conversions between gal/lb (US) and ft³/lb arise in steam-table lookups, compressible-flow analysis, and thermodynamic state-point work. Specific volume is the reciprocal of density and must not be confused with it — m³/kg and ft³/lb appear directly in property tables and equation-of-state solvers.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
